I'm not sure either and am surprised that they do degrade. I thought light, air and heat were the cause of degradation. I have frozen weed before and as long as it is dry and you are careful defrosting it so you dont break off the brittle trichromes it stays the potient for years. Butttt the capsuals do change. I noticed no difference after 3 months but after 5 months, I had to throw the rest away. So I would say safely 3 months.
